Crash Analysis

Overview

Crash Analysis is a configuration of ArcGIS Pro that can be used by public works, public safety, and transportation departments to analyze crash data and identify streets and intersections where concentrations of serious and fatal crashes occur. Crash Analysis includes a collection of tools that merge similar road segments together based on key properties, assign crashes to road segments, and create four standard crash risk maps which help inform decisions regarding safety improvement priorities or crash mitigation measures.

In many communities a high percentage of severe injury or fatal crashes occur on a small percentage of the streets. Crash Analysis can be used to identify the streets and intersections, also called the High Injury Network, where concentrations of serious and fatal crashes occur. The results can be used to plan capital improvements that lead to safer roadways and intersections and can be shared with the general public using the High Injury Network Locator application to enhance education and enforcement activities. In many cases, Crash Analysis serves as a foundation for Complete Streets or Vision Zero initiatives adopted by government agencies to reduce fatalities or serious injury on roadways in their community.
